Clarification on IFF4 unknown response behaviour?

Can someone please clarify what is the correct IFF4 behaviour to unknown response. There are various threads on this but I haven't seen a definitive answer to this.

TMS left short, response with a yellow square shown in - DCS Stable version, Wag's videos (e.g. November 2022 Update), NCTR Training mission, etc.

No response - current DCS OB behaviour, various people contributing to threads here on this.

Just curious to know.

The only AIFF response would be a friendly (correct code) as indicted by a green 4 and circle. The amber box seen earlier was incorrect. AIFF is not tied to the radar and ROE tree.

thanks

I gave a little more in-depth explanation recently in another thread:

 

-Col. Russ Everts opinion on surface-to-air missiles: "It makes you feel a little better if it's coming for one of your buddies. However, if it's coming for you, it doesn't make you feel too good, but it does rearrange your priorities."

Yes, I started that thread and I appreciated your detailed explanation.  I was just looking for official confirmation that the behaviour had changed in DCS as TMs and Wags's videos show the yellow square as an unknown response. BN has confirmed that a change was made.

We believe it is correct as is based on available public information.

It should not overlay the radar contact as it would obscure. 

If you have public information to suggest otherwise please PM me. 

thank you
